Most numerical studies are limited to close boundary schemes, which, however, suffer from severe finite size effects. To overcome this discrepancy we have developed a semi grand canonical molecular dynamics simulation scheme for complex fluids. With this method we study the concentration driven reentrant collapse and swelling transition of poly(N-isopropylacrylamide) (PNIPam) in aqueous methanol and demonstrate the role of the delicate interplay of different intramolecular interactions. It was found that, even though the chains collapse upon increase of methanol content, the chemical potential of the monomers continues to decay, i.e. in terms of a classical phase transition picture the solvent remains to be a “good solvent”. This can be explained in terms of a very general theoretical picture, which demonstrates that this scheme applies to many polymers in mixed solvents.

CCPP Lounge High Energy Physics Seminars (hep) Seyda Ipek University of Washington CP Violation in Pseudo-Dirac Fermion Oscillations Supersymmetric theories with a U(1)_R symmetry have Dirac gauginos, solve the supersymmetric flavor and CP problems, and have distinctive collider signatures. However when supergravity is included, the U(1)_R must be broken, adding small Majorana mass terms which split the mass of the two components of the Dirac gaugino and lead to oscillations between U(1)_R charge eigenstates. I will present a general study of fermion-antifermion oscillations in this system, including the effects of decays and CP violation. I will show that this CP violation can be observed as a same-sign dilepton asymmetry.

Here, I focus on the phase structure of these models in the framework of the nonperturbative functional renormalization group, specifically addressing the low-energy properties in the vicinity of the interacting fixed point governing the dynamics of the chiral symmetry breaking transition. This approach circumvents the problems of a purely perturbative approach close to criticality and allows us to follow the flow of this model into the symmetry broken phase. Introducing composite degrees of freedom for the order parameter, this model exhibits a continuous phase transition in the universality class of a three-dimensional matrix Yukawa model. I will discuss extensions of this work to the transition to the quantum anomalous Hall phase, as well as multicritical behavior and phase structure in the case of competing order parameters.

Our group at Virginia has been studying the effects of the ambient plasma on the surfaces and atmosphere of a number of solar system bodies being visited by spacecraft.

These planets have no analogues in our Solar System, providing a potentially revolutionary opportunity to assess planet formation and evolution processes for a new planetary population. By coupling theoretical work with sophisticated statistical modeling, we place quantitative constraints on the distribution of physically relevant properties, such as planet compositions, while accurately incorporating the large uncertainties and biases in the Kepler data. We first apply this framework to the composition distribution of Kepler's sub-Neptunes: assuming an internal structure consisting of a rocky core with a hydrogen and helium envelope, we find that these envelopes are most likely to be ~ 1% of these planets' total mass with an intrinsic scatter of 0.5 dex. Our results do not produce a one-to-one relationship between super-Earth masses and radii. Accordingly, we derive a probability density function that incorporates the intrinsic scatter in planetary masses at a given radius, which provides dynamical studies a more appropriate means to map Kepler radii to masses. Finally, we present first results from our campaign to detect stellar companions to Kepler super-Earth host stars using the laser guide star adaptive optics systems at Lick Observatory, and discuss implications for the orbital evolution of this entirely new class of planets.

We theoretically derive the stability criteria and calculate the three-dimensional magnetic switching diagrams for bilayers with perpendicular magnetic anisotropy. Focusing on the case of applied field directed in the plane formed by the bilayer normal and the in-plane current, we find that the spin torque creates an additional stable equilibrium of the ferromagnet. As a result, two scenarios of magnetic switching are possible: (1) conventional up'' to  down'' switching and (2) switching to the new equilibrium. The critical conditions for different switching scenarios are analysed in terms of the switching phase diagrams. October 27, 2014 Monday 12:30 PM  + Meyer 5th Fl.

The structure of this protected chiral algebra reflects the physics of the parent four- or six-dimensional theory in interesting ways. In many cases the relevant chiral algebra can be given an economical description as a W-algebra. Applications of this structure include the derivation of new unitarity bounds for four-dimensional SCFTs with global symmetries and the computation of three-point functions of half-BPS operators in the (2,0) theories at finite central charge.

CCPP Lounge Other CCPP (ccpp) Informal Astro Talk Andreu Font-Ribera LBNL Studying the Expansion of the Universe with BOSS quasars After five years of observations, the Baryon Oscillation Spectroscopic Survey (BOSS) was finished in July. During these years, it has used the SDSS telescope to obtain spectra of 1.5 million galaxies to get very accurate measurements of the Baryon Acoustic Oscillations (BAO) scale at redshift z ~0.5. Roughly 20% of the fibers of the spectrograph, however, are pointing to high redshift quasars with the goal of detecting the BAO feature in the clustering of the intergalactic medium, using a technique known as the Lyman alpha forest. In this talk I will overview several recent results from the Lyman alpha forest working group in BOSS, including the measurement of BAO at z=2.4 both from the auto-correlation of the Lyman alpha absorption, and from its cross-correlation from quasars. I will also present preliminary results on the cosmological parameters constrains obtained when combining all BOSS BAO analyses with Cosmic Microwave Background and supernovae probes, including the most precise measurement of the current expansion of the Universe.

CCPP Lounge Astrophysics and Relativity Seminars (astro) Alyson Brooks Rutgers University Re-Examining Astrophysical Constraints on the Dark Matter Model The cosmological model based on cold dark matter (CDM) and dark energy has been hugely successful in describing the observed evolution and large scale structure of our Universe. However, at small scales (in the smallest galaxies and at the centers of larger galaxies), a number of observations seem to conflict with the predictions CDM cosmology, leading to recent interest in Warm Dark Matter (WDM) and Self-Interacting Dark Matter (SIDM) models. These small scales, though, are also regions dominated by the influence of baryons. I will present results from high resolution cosmological galaxy simulations that include both baryons and dark matter to show that baryonic physics can significantly alter the dark matter structure and substructure of galaxies, revolutionizing our expectations for galaxy structure and influencing our interpretation of the Dark Matter model.

CCPP Lounge Other CCPP (ccpp) Informal Astro Talk Tsvi Piran Hebrew University Gamma Ray Bursts and Life As a copious source of gamma-rays, a nearby Galactic Gamma-Ray Burst (GRB) can be a threat to life. Using recent determinations of the rate of GRBs, their luminosity function and properties of their host galaxies, we estimate the probability that a life-threatening (lethal) GRB would take place. Amongst the different kinds of GRBs, long ones are most dangerous. There is a very good chance (but no certainty) that at least one lethal GRB took place during the past 5 Gyr close enough to Earth as to significantly damage life. There is a 50% chance that such a lethal GRB took place during the last 500 Myr causing one of the major mass extinction events. Assuming that a similar level of radiation would be lethal to life on other exoplanets hosting life, we explore the potential effects of GRBs to life elsewhere in the Galaxy and the Universe. We find that the probability of a lethal GRB is much larger in the inner Milky Way (95% within a radius of 4 kpc from the galactic center), making it inhospitable to life. Only at the outskirts of the Milky Way, at more than 10 kpc from the galactic center, this probability drops below 50%. When considering the Universe as a whole, the safest environments for life (similar to the one on Earth) are the lowest density regions in the outskirts of large galaxies and life can exist in only ≈ 10% of galaxies. Remarkably, a cosmological constant is essential for such systems to exist. Furthermore, because of both the higher GRB rate and galaxies being smaller, life as it exists on Earth could not take place at z > 0.5. Early life forms must have been much more resilient to radiation. November 7, 2014 Friday 11:30 AM  + Meyer 5th Fl.

This line was detected at more than 3-sigma statistical significance in five independent samples of XMM-Newton. The lack of any atomic transitions at this energy in thermal plasma, hints that the line could be a signature of decaying sterile neutrinos.

Such exchange is permitted by active transport, also called intracellular trafficking, of vesicles along the cytoskeleton (actin filaments, microtubules), and mediated by molecular motors. In order to perturbate this intracellular trafficking, two different ways to apply controlled physical stresses have been performed. The first perturbation is a mechanical one: we used magnetic endosomes to apply a mechanical stress to the cell body and to probe the activity. To obtain them, we internalized magnetic nanoparticles into mesenchymal stem cells (MSC) through the natural endocytosis pathway. These endosomes align into chains in the presence of a magnetic field. The mechanical perturbation then consists in applying a rotational magnetic field on these chains. When comparing the activity before and after a shear stress, we observed a small decrease in the intracellular activity. The second perturbation has a photochemical origin, through the excitation of internalized photosensitizer molecules (m-THPC or TPCS2a) into prostatic cancer cells (PC3). By combining measurements of local cytoplasmic viscosity and intracellular activity, we found that the photo-activation induced only a slight increase in viscosity while a massive slowing down of trafficking was observed. These effects are correlated with the depolymerization of the microtubule network. The experiments demonstrate that these two photochemical agents have different intracellular impacts. Eventually, we studied a second effect of the photochemical perturbation which is the massive and rapid emission of extracellular vesicles directly after the treatment.

Among the techniques currently used to discover extrasolar planets, microlensing has some unique capabilities. It is the most sensitive technique to detect planets beyond the "snowline", where gas and ice giants are likely to form. Starting April 2011, we have begun a "second generation" microlensing survey, combining OGLE, MOA, and the Wise observatory. I will present a preliminary statistical analysis for the first three seasons of the survey. Over 10% of the events that were observed by all three sites showed a deviation from a single-lens microlensing, and for almost 1/3 of those the anomaly might be explained by a planetary companion. By accounting for our detection efficiency, we find a ~20-25% planetary system abundance, which is in line with previous microlensing estimates. Moreover, our results suggests that massive planets around low-mass stars are common, which may be in conflict with planetary formation scenarios. The data also can set constraints on the multiplicity fraction and the binary mass ratio distribution. November 21, 2014 Friday 11:30 AM  + Meyer 5th Fl.

There is experimental evidence for them near the quantum critical point both in cuprates and near the Anti-ferromagnetic critial point in Fe-based superconductors and in some heavy Fermions. The dissipative Quantum XY-Model, proposed initially to describe the superconductor to insulator transition in thin films, with an anisotropic generalization, describes both. I will summarize an analytical solution of the model which derives local quantum critical fluctuations for this model as due to the proliferation of a class of topological exciations and supplement it by Monte-Carlo calculations on the model.

CCPP Lounge Astrophysics and Relativity Seminars (astro) Michael Kesden UT Dallas The gravitational-wave signatures of astrophysical binary black-hole formation Binary stars of sufficient mass can collapse into binary black holes at the end of their main-sequence evolution. These binary black holes emit gravitational waves that extract energy and angular momentum from their orbit, cauing the black holes to inspiral and eventually merge. Mass transfer and tidal alignment during the evolution of the black hole's stellar progenitors can induce an asymmetry in the misalignment of binary black-hole spins with the orbital angular momentum. If binaries preferentially form with the the spins of the more massive black hole more (less) aligned with the orbital angular momentum than that of the less massive black hole, the components of the spin in the orbital plane will preferentially align (anti-align) during the gravitational-wave induced inspiral. Once trapped in these spin-orbit resonances, the orbital angular momentum and both spins jointly precess in a common plane during the remainder of the inspiral. We examine the gravitational waves emitted by binary black holes in these resonant configurations, and find that binaries with aligned spin components in the orbital plane can be distinguished by the greater precession of the orbital plane. This precession leaves a distinctive signature in the gravitational waveform which can be identified by ground-based gravitational-wave detectors in sources with sufficient signal-to-noise ratios, allowing gravitational-wave observers to distinguish different scenarios for binary black-hole formation.

In addition to celebrated fluctuation theorems, stochastic thermodynamic now provides both a nice unifying theoretical framework and a useful way for studying these systems experimentally. It was for instance at the heart of the first experimental verification of Landauer principle. After reviewing the classical case, I will propose an attempt to construct a quantum stochastic thermodynamics based on a quantum trajectory description of driven open systems. This framework allows for definitions at the single trajectory level of basic thermodynamic quantities such as heat transfer, work and entropy in the quantum regime. It can then be used to obtained “central” fluctuation theorems, from which follow more"practical" fluctuation relations such as for instance Jarzynski and Crooks fluctuation theorems. I will discuss in particular similarities and differences between the ħ=0 and ħ=1 regimes. December 3, 2014 Wednesday 2:00 PM  + Meyer 5th Fl.
